This segment -- take a look at the high -- nozzle. A device that enables the fire service to get water on to a fire -- -- highrise building where we're out of reach of any exterior streams be it from -- -- -- -- -- the ground or adjoining balcony. Let's take a -- don't look at this device. That we look here. Is roughly an eight foot long piece of one and a half inch tubular aluminum. -- -- send. We have a simple two and a half -- -- out. Here we have the -- handle -- and place it gives us some maneuverability of the nozzle when it's in place flowing water into the floor above. Where the flyers located. Here we have -- trusting system which gives rigidity to this pipe. Because we'll go to get a tremendous amount a downward force when the -- is flowing. That keeps it nice and tight in laws to control extreme. At the far end. At the tip we have an inch and a tip so with a two and a half inch line an inch and a tip that's the same combination. Of hole is in novels we use -- our standard all right -- It also. Won't allow any clogging factor to a car also Illinois and our testing on Governors Island 2008. We actually found that the solid -- tip flowing in -- hitting the ceiling of the fire room. Basically turning on a sprinkler head. Knocked the fire down rapidly cooling everything down during the fog Tim was not as effective as a solid bulletin. The -- -- nozzle is fourteen pounds is easily transported in elevators and up stairwells. To -- a high -- nozzle. The engine company simply -- to place the nozzle on the windowsill. Given a slight tilt to one side. And when ordered opened the nozzle. The water will Begin to flow hitting the side of the building adjacent to the window. Slowly that company will push the nozzle out. And at the same time Begin to bring the nozzle. Square up pointing straight up. The stream now should be hitting -- -- Andrew war between the floor below window and the fire window with a target window. At that same time with a warning him to spend jewel able rained down and you'll hear the actual -- what is stream hitting that's manageable you continue to push out. -- the sound disappears and water is no longer raining down at that point. You know that should these stream is in the window deploy hitting the ceiling above the fire knocking defied them. Yet the company can also wiggle -- nozzle. Which will -- more water in the fire area if the roughly thirty seconds they can then shut down. And as they shut down slightly -- the nozzle to decide to -- a slug does not hit them. On the floor below. And then we look the conditions on the -- -- if they've changed. And we've knocked the -- them. There will be times a direct frontal attack will not be capable in these type abilities and highrise buildings so this device will actually allow -- to get some water on the fire on the floor below again making for a much safer operation in these type of challenging fires. I'm lieutenant John zarrella thank you for watching training minutes.
